Each row holds a unique set of parameters for a matrix population model. This reflects diverse recovery (conservation action) and extinction (threat) scenarios.
dt <- pop01_param_poun()
The first few rows should look like this….
| species | type | first_year | a1 | a2 | a3 | a4 | b1 | b2 | b3 | b4 | c1 | c2 | c3 | c4 | d1 | d2 | d3 | d4 | akey |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Podocnemis unifilis | base | 0.0 | 0 | 0 | 0 | 10.74 | 0.0 | 0.33 | 0 | 0 | 0 | 0.17 | 0.29 | 0 | 0 | 0 | 0.11 | 0.93 | poun_base_0 |
| Podocnemis unifilis | base | 0.1 | 0 | 0 | 0 | 10.74 | 0.1 | 0.33 | 0 | 0 | 0 | 0.17 | 0.29 | 0 | 0 | 0 | 0.11 | 0.93 | poun_base_0.1 |

The rows can be easily converted for use in a stage-based matrix population model. The first row becomes the following stage-based matrix, where columns reflect the stage and rows what to the stage at time + 1.
stage_names <- c("a1", "a2", "a3", "a4",
"b1", "b2", "b3", "b4",
"c1", "c2", "c3", "c4",
"d1", "d2", "d3", "d4")
vpop <- unlist(dt[3 , stage_names])
pop_mat <- matrix(vpop, byrow = TRUE, ncol=4)
dimnames(pop_mat) <- list(c("a", "b", "c", "d"),
c( "a", "b", "c", "d"))
The matrix should look like this:
| a | b | c | d | |
|---|---|---|---|---|
| a | 0.000000 | 0.000000 | 0.000000 | 10.741500 |
| b | 0.200000 | 0.333333 | 0.000000 | 0.000000 |
| c | 0.000000 | 0.166667 | 0.285714 | 0.000000 |
| d | 0.000000 | 0.000000 | 0.114286 | 0.930000 |
This matrix includes information of population growth and survival and reproduction.

RedList guidelines p38
For example, upper and lower quartiles of the projected magnitude of the
future reduction (i.e., reductions with 25% and 75% probability) may be
considered to represent a plausible range of projected
reduction
Green Status Viability
A species is considered viable in a spatial unit if application of the
Regional Red List Guidelines to the population in the spatial unit would
result in a categorization of ‘Least Concern’ OR ‘Near Threatened and
Not Declining’.
